XPP Foam
In terms of classification by type, the extruded polypropylene (XPP) foam market is divided into low-density XPP foam and high-density XPP foam. For applications that require lightweight materials, such as protective packaging and automotive parts, where weight reduction is necessary, low-density XPP foam is used. It has excellent shock absorption and cushioning capabilities while maintaining structural integrity.
The product uses polypropylene as the main raw material. Through irradiation, the internal spatial structure of polypropylene molecules is changed, turning them into a cross-linked network molecular chain structure. Then, through high-temperature foaming, it forms a closed-cell foaming material with an independent cell structure. The current expansion ratios are 5, 12, 20, and 30.
One of the main characteristics of XPP foam is its light weight, which provides significant advantages for applications where weight reduction is highly valued. XPP foam has a low density but still maintains structural integrity and offers reliable protection against impacts and vibrations. Due to its closed-cell structure, it ensures high insulation quality, making it an excellent choice for thermal insulation applications. In addition, XPP foam is waterproof, which enhances its durability and prevents performance degradation caused by water absorption.
Fire Retardancy HF-1: XPP foam (irradiation cross-linked polypropylene foam) has excellent flame-retardant properties. XPP foam achieves its flame-retardant performance by adding flame retardants, which usually include a variety of compounded flame retardants that work synergistically to achieve the flame-retardant effect. Insulation and High Voltage Resistance: It has excellent electrical insulation properties and can effectively prevent the generation of static electricity. It is widely used in new energy vehicles, packaging, construction, and other fields.
